Fuji Electric FRENIC MEGA G2 Series - Guideline for Selecting Inverter Specification and Capacity

10.4 Selecting the Inverter Rating Specification (HHD/HND)
10-16
10.4.2 Guideline for selecting inverter specification and capacity
Table 10.4-1 shows the functional differences between the HHD/HND specifications.
Provided that the application is satisfied with the HND specification in terms of both overload capability and
functionality, an inverter capacity (HND specification) one to two ranks lower than the capacity of the motor being
used can be selected.

Capable of driving a
motor whose capacity is
the same as the inverter
capacity.
Capable of driving a motor
whose capacity is one to
two ranks higher than the
inverter capacity.
In the case of the HND
specification, the continuous
current rating is one to two
ranks higher, but the
percentage (%) drops
relative to the continuous
current rating of the
overload capability. Refer to
“Chapter 12
“SPECIFICATIONS”" for
details.

With the HND specification,
a value out of the range, if
specified, automatically
changes to the maximum
value allowable for the HND
specification.
